Stochastic optimization by message passing
Fabrizio Altarelli, Alfredo Braunstein, Abolfazl Ramezanpour +1
Most optimization problems in applied sciences realistically involve uncertainty in the parameters defining the cost function, of which only statistical information is known before…
Inference and learning in sparse systems with multiple states
A. Braunstein, A. Ramezanpour, R. Zecchina +1
We discuss how inference can be performed when data are sampled from the non-ergodic phase of systems with multiple attractors. We take as model system the finite connectivity Hopf…
Estimating the size of the solution space of metabolic networks
Alfredo Braunstein, Roberto Mulet, Andrea Pagnani
In this work we propose a novel algorithmic strategy that allows for an efficient characterization of the whole set of stable fluxes compatible with the metabolic constraints. The…
